摘　　要：本文基于现行的行业规范与国家标准图集,从电源系统的功能分类与术语定义出发,通过深入解析规范文献的具体条款与图集实例,探讨了多电源供配电系统中多种主接线方案的应用适宜性。结合理论分析与实践案例,旨在纠正电气设计中的常见认知偏差与错误,强化系统安全稳定性,为电气工程师提供理论与实践兼备的参考。文章重点讨论了正常电源、备用电源与应急电源的定义与区分,以及在设计中如何准确应用这些电源以满足不同负荷等级的需求,特别是特级负荷的供电保障。Based on current industry regulations and national standard drawings,this article begins with the functional classification and terminology definition of power supply systems.Through in-depth analysis of specific provisions in regulatory documents and practical examples in drawings,it explores the suitability of various main connection schemes in multi-power supply and distribution systems.Combining theoretical analysis with practical cases,the article aims to correct common cognitive biases and errors in electrical design,enhance the safety and stability of the system,and provide electrical engineers with both theoretical and practical references.The article focuses on defining and distinguishing between normal power sources,standby power sources,and emergency power sources,as well as how to accurately apply these power sources in design to meet the needs of different load levels,especially the power supply assurance for critical loads.
